Northcote Avenue, London W5

A turntable in the private garage will rotate your car to save you backing out. But you don’t need to drive to see London, for this 1,862 sq ft penthouse is wrapped by a terrace with views across town. There are only two bedrooms though. Asking price: £1.35m. Barnard Marcus, 020 8579 5050

The Beacon, Hemel Hempstead, Hertfordshire

This buiding reckons it’s the world’s most sustainable tower, with a promise of a lifetime of free energy from solar panels. Cars are parked by automated technology in the undercroft: simply drive to the entrance, turn the engine off and go to bed while the machines safely stow it. That idyll does not yet exist. You have to buy off-plan and wait until phase three is completed at some unspecified time. Cost: From £217,950. The Beacon, 020 3283 8583

Palmeira Avenue, Hove, East Sussex

Automatic shutters roll up as you drive up to the underground car park and a lift lowers the vehicle to your two allocated spaces. Two of the four roof terraces off this penthouse overlook the Sussex county cricket ground. Your million buys you only three bedrooms. Asking price: £995,000. Mishon Mackay, 01273 829 300
